27/8/2018
Summary
The aim of this document is to explore the representation of taxa categoryes with at least one endangered species in some of the United States National Parks; first, in general, graphics include non vascular plants, invertebrates and other non-chordate taxa; second, I show the representation of the chordate taxa classified as endangered. Analysis were run exclusively for endangered species in some of the biggest Natural Parks in USA. Due to the lack of knowledge about encoding and the subsequent impossibility for this program to recognize the tilde, this document will be presented totally in english.
